One Direction's Niall Horan stopped by The Tonight Show Starring Jimmy Fallon Thursday night (May 25), where he playfully peer pressured the talk show host into doing the infamous "Gangnam Style" dance from K-pop superstar Psy's iconic music video.

Interrupting Jimmy Fallon's opening monologue, the "Slow Hands" singer quipped, "Your jokes are funny but come on, give the people what they want! Everyone wants to see you dance."

The talk show host scoffed and asked, "What dance are you talking about?"

"Obviously Gangnam Style," Horan replied, as the audience burst into cheers and Fallon began protesting.

"I don't even know how to 'Gangnam Style,'" he pleaded, but as soon as the music kicked in, both the late night personality and pop star found themselves joyfully performing Psy's famous galloping move.
